I've had a request that students be allowed to use laptops tomorrow instead of printing materials, since there are several items to print, so if you would like to bring your laptop with the readings, that is all right for tomorrow.
Please be sure to mark up the .pdf versions (comments, etc.) as you would a regular text. If you have a Mac, you can do this in Preview; if you have a Windows laptop, Adobe Reader X will let you make comments in a .pdf file. See the FAQ for details and to download this version: http://www.adobe.com/products/reader/faq.html.
